# First detection of atmosphere on rocky, temperate exoplanet

Scientists have for the first time detected an atmosphere around a rocky, temperate exoplanet, likely using the James Webb Space Telescope. The planet, located in its star's habitable zone, offers a key target for studying potential conditions for life beyond Earth. This breakthrough advances efforts to characterize Earth-like worlds and search for biosignatures.
